Emily Blunt's mother lives up to the actress' last name when it comes to love.

In "The Five-Year Engagement, the British star and Jason Segel play a couple who keep delaying their wedding after being forced to move to Michigan for a job. They talked to OnTheRedCarpet.com about their own parents' less-than-smooth engagement stories.

"My father proposed to my mother with a cigar band because he couldn't afford a ring at the time," Segel said.

In "The Five-Year Engagement," Segel's character leaves San Francisco to be with his fiancé. He and Blunt opened up about their experiences making sacrifices for past relationships. Blunt and "The Office" star John Krasinski wed in 2010.

"I actually always want to do things that you know will mean the world to them, so for me, it's never about not wanting to do it," Blunt said. "I think when you're really in love and you're really happy, the joy I get from doing things that would make him happy is huge."

"I was completely unemployed during my relationship, so I had nothing to put on hold," Segel said. "It was on hold. It was being held."

Segel, 32, who also co-wrote the movie, is currently said to be dating actress Michelle Williams. The actress attended the premiere of "The Five-Year Engagement" at the Tribeca Film Festival on April 18.

Although the couple didn't pose for pictures together, they were spotted cuddling together at an after party. People magazine reported that they were affectionate all night, whispering in each other's ears and exchanging the occasional kiss on the cheek.

"Usually its boy meets girl, they don't like each other, then they kind of fall in love and ... that's how it ends and it's predictable. Even though I knew what's going to happen in the end, because I'd read the script, obviously, but when I saw the movie, I thought 'Wow, it's quite ambiguous as to what's going to happen to them and you're not kind of sure,'" she said.

"I think you really see the plight in it for these two and you invest in them, even though its super funny and outrageous, the situations they're put in, I think it's a very real exploration of a relationship and all the ups and downs of it," the actress added.

"The Five-Year Engagement" also stars Alison Brie of "Community" and Chris Pratt of "Parks & Recreation," who add to the film's comedic value.

"We were so lucky with those two because when the four of us had a scene together, it was like my favorite day ever," Blunt said about her co-stars. "There were times where I was just helpless, crying with laughter and unusable in any of my takes because it was a riot, really."

"It truly was the best movie-making experience I've ever had," Segel agreed. "We had so much fun."
